Show answer & explanation
Correct answer: C
Concept: In a blood-relations puzzle, build the family tree one stated relation at a time and tag each member's gender and generation directly from the relational term used (husband, wife, brother, sister, son, daughter, mother, father) - only once every member is placed can roles be counted correctly.
A and B are a married couple, and A is stated to be the male member, so A is the husband and B is the wife.
C is the brother of A, placing C in A's own generation as a male.
D is the only son of C, placing D one generation below, as a male; E is the sister of D, so E is C's daughter, a female.
B is the daughter-in-law of F, meaning F is a parent of B's husband A; since F's husband has died, F is the widowed mother of A (and of C).
Cross-check: Listing every member with the gender fixed by these relational terms: A - male (husband), B - female (wife), C - male (brother), D - male (son), E - female (sister/daughter), F - female (widowed mother).
Result: Counting the male members - A, C, and D - gives a total of three male members.
